VSCode WebVTT Extension and some additional questions

Hi WebVTT Community,

I wanted to quickly introduce myself and ask a couple of questions
pertaining to WebVTT. Last year I spent a couple of days putting together
some basic syntax highlighting for WebVTT, and published it on the VSCode
marketplace, you can check it out here:

https://marketplace.visualstudio.com/items?itemName=spaceribs.webvtt-language
https://github.com/spaceribs/vscode-webvtt-language

I built it because I've been using the WebVTT spec for my own project:

I completely forgot about this extension after publishing it, up until last
weekend when I received a pull request
<https://github.com/spaceribs/vscode-webvtt-language/pull/1> to make the
syntax highlighting work better with some details of the spec. That's when
I also noticed my extension was still the only WebVTT extension in the
marketplace, and is currently installed by ~4.2k users.

Now that you know the context, I'd like to ask a few questions:

   1. Is the WebVTT logo on the github the official WebVTT logo? Does a
   vectorized version exist of it and can I use it rather than my hastily put
   together logo set for this extension?
   2. My extension is pretty bare bones with just syntax highlighting. I'm
   happy to maintain this project, but what kind of features do most vtt
   coders expect when writing captions and where should I take this project
   next?

Thanks,
-Aaron
